About this 3D model
This is a remix of the following design on Thingiverse: Aquarium pump nozzle by Zak26 The model has been upscaled to fit a 16mm diameter nozzle. In my particular use case, this fits snug on a SunSun JP-024F 317 GPH Aquarium Powerhead Water Pump with Internal Filter (Amazon link here ). May fit on other models if the pump outlet is 16mm diameter.
